This composition when applied on an electrical conductor will effectively insulate it. The resultant mass is pliable and very slightly sticky, and Will retain its original. properties for an indefinite-period. The cement gives it body and binds the compound While the oil appears toform a solvent which permits of a close mixture of the cement and tar.

What I claim as my invention is:

1. An electrical insulating compound consisting of coal. tar eightgallons, kerosene oil two gallons, Portlandl'rcement two gallons and Japan drier one gallon.

2. An electrical insulating compound com prising coal tar 8 gallons, kerosene oil two gallons, Portland cement two gallons and Japan drier.
